What are the methods for rust removal of CNC parts? General iron products will rust. This is basic common sense. Many people know it. Then CNC parts processing or accessories are used as bearings, etc. due to inventory conditions or improper rust prevention, for example, it is prone to rust. In the case of rust, it is basically impossible to use mechanical methods to deal with it. Chemical pickling will damage the accuracy of parts, so what method can be used to remove rust? Here's what I've learned from my experience:

There is no damage to the workpiece, the parts will not change, and they will not be corroded. High precision part rework or repair. Floating rust is formed on the surface of the parts due to improper inventory or transportation. The use of Colleen-306 can perfectly remove the floating rust and ensure the original accuracy.

1. Immersion cleaning process:

1 Add the professional cleaning stock solution to the tank (it is recommended to use a plastic or stainless steel tank, which can reduce the penetration of iron ions into the stock solution and reduce the service life);

2 Use an electric heater to heat it to 40-50 degrees and keep it at room temperature, but it only needs to extend the time;

3 Soak the metal processing parts into the tank;

2. Wipe cleaning process:

1 Repeatedly wipe with a rag, this method is suitable for cleaning and rust removal of large equipment or workpieces;

2 After wiping, dry it with hot air or dry it naturally and then apply anti-rust oil.
